Broken valve stem?

I just got my 09 Jeep Wrangler 2door, the tire pressure light came on. I went to check the pressure and noticed the valvestem on the spare and my drivers side rear were broken. Not leaking air but just broke. Should I just put a rubber valvestem in it or change the whole tire pressure sensor and all?

No need to buy new sensors unless yours are dead.

If your '09 TPS sensors are like my '10s, the sensors are held to the valve stems by a single screw.

You need the right type of valve stem (widely available), but it's a fookin' cake walk.

Break bead --> remove 1 screw + sensor --> R&R valve stem --> reinstall sensor --> reinflate tire




EDIT: oh, and (personal preference) - get SHORT valve stems.



EDIT2: oh, and Welcome to JKO!

I did a write-up about this on my '09 a while back. Not sure if links and pics are still good but hopefully it's helpful. You should be able to do a little research/googling and find what you need for cheap.

TPMS & Valve Stem fix

Edit: I just updated that thread with some new links that should be more helpful.

That's great! Thanks for maintaining / updating our collective JKO knowledge base.

Bummer: the '09s don't have the same style as my '10s



For comparison, here's an '09 sensor (photo courtesy of Joe C):


If anyone has to change all TPMS sensors on an earlier model, I'd go to the newer style.

Flexible valve stem with sensor screwed on to the inside end, with room to wiggle and deflect without cracking (I've tested this theory )

So on my 09 it's a one piece? That sucks, I was hoping to just put a rubber valvestem in it.

You can't put rubber stems in and keep the stock TPMS but the aluminum stem is separate from the sensor so you can replace just the stem.

only because it relates to breaking a valvestem - FWIW I do not run TPMS sensors as I am the most OCD mofo in the world and check my tire pressure before I take off even to get kids at bus stop or to drive someplace so I am sort of my own TPMsystem, heh- I will remind anyone else that is reading this that for when this occurs on the trail and you are spareless or whatever reason , these things are great to carry in your tire plug kit or glovebox.

ExWrench reminding to use the short stems is great advice, too.,

If your sensors are good and you want to keep the current valve stem type, they're not horribly expensive.
If you're going to wheel it and rub your valve stems, I'd go the flexible route.
If you've got money to burn, you could buy new-style sensors and stems.

If your sensors are good and you want rubber stems, you could attach the sensor inside the center drop-out.
I won't say how I would attach it, because I don't want you suing me if you fuck anything up.

Wow j3ff3ry, I genuinely admire your level of diligence regarding tire pressure
. . . though I will not be emulating said admirable diligence

Dood! - Y'all just dun lurned me sump'n Thanks j3ff3ry!
Some fahhhrrrking genius combined well nut + valve stem = kickass band aid!
I hope he or she profited from this creative solution.

leave it to you to have your own, beefier, self-made version that probably was around before the ones I suggested. Nice, man.
I don't think they have been out too long , maybe 3 years ?

And on subject of what could be misinterpreted as a psi fetish, trust me it's grown annoying . I only have to be that diligent because not having properly nor completely cleaned some particularly gooey Alabama clay mud from my inner wheel where the bead mates to it while aired down where it all accumulated and then dried , I have only one that retained air for more than a day ...slow, varying leaks that were a pita . I just had my tires flipped and remounted two days ago , went down this morning to verify and sure enough they are all holding at the psi I filled them to ystrdy ; holy hell, wtf am I gonna do now with all my free time ?!

it is odd having the bfgs with the WLO but I don't use 'tires for looks ... : jeep2:

To be clear, I didn't know about emergency valve stems at all until clicking your link - thanks for the ed-juh-mah-cay-shun! In researching this new-to-me wonder, I first found a few different colors of the wing-nut style, then the "permanent" ones w/o the plastic wing nut, then the permanent-style shorties (all made by Colby, so their patent is still solid and the sneaky Chinos haven't found a way around it yet). When I gazed upon the elegant simplicity of design, combined with the minimal liability of extension, those expensive little brass and rubber contraptions said
"I'm your huckleberry", and I could not argue to the contrary.

Here's my trick: running my tires at 26, I set my TPMS threshold to 30 psi. Experimentation has shown me that my TPMS goes off 4 PSI below set point. If I get a pound under 26, dash nanny informs me that tires need a-checkin'. Unless dash nanny bitches at me, my lazy ass only checks tire pressure before road trips or it's been awhile and paranoia is creeping in.
